最近的调查数据揭示在美国男性和绝经后女性中，随着铁缺乏的普遍减少，血清铁蛋白已经有所升高。这些发现已经引起人们对正常成人和血色素沉着症基因携带者，当饮食中铁含量较高时，有效限制贮存铁的生理机制的关注。另外，最近的流行病学调查也发现贮存铁轻度升高（以前认为是安全的范围）对缺铁性心脏病和癌症患者可能是一个危险因素。由于还不知道体内贮存铁升高对人体的益处，目前要谨慎地避免人体内贮存铁的进一步升高，减少男性和绝经后女性饮食铁的摄入，这组人群的铁的摄入明显超过了目前的饮食推荐量（ＲＤＡ），饮食铁及其它影响血清铁蛋白升高的因素均有待于证实
Recent survey data reveal that serum ferritin has increased in the United States and postmenopausal women as a general decline in iron deficiency. These findings have drawn the attention of people with normal adult and hemochromatosis gene carriers that an effective limitation of the physiological mechanism of iron storage when the iron content in the diet is high. In addition, a recent epidemiological survey also found that mild iron storage (previously considered to be safe) may be a risk factor for patients with iron deficiency heart disease and cancer. Since the benefits of elevated iron in the body are not known to the human body, it is now prudent to avoid further increases in stored iron in the human body and to reduce the dietary intake of iron in men and post-menopausal women, which significantly exceeds iron intake The current dietary recommendation (RDA), dietary iron, and other factors that affect the elevated serum ferritin are yet to be confirmed
